Be it known that l, C l-Ifxnmis L. B Uluneli, a citizen of the Uniteditntes, residing at- Lo'ndon, in'llieeo1m-ty ot Middlesex, Eng-- land,have invented :1 eel-tuin ne and nseiul lrnprovenmiit in Sheet or Cn1d'l ii!lie1's, of which the following is n fulholear, ooicise,' and eK-actdescription, rei'erence being had to Ilthe uceqinponying drawings,forming a' part efihis specification.

My invention relates' to un improved device for removing .sheets orcords one ato, tilne lfrom u pile ot such cards. It is par ticnlurlividnpled for use in connection with processes requiring work onsheets or'cards while they1 are in :x pile, `without disturbing the arrangelnem'of the pile.

M v invention 1s limrt-lcnlnrly ndipi'cd for Ause ln eonnection with theimprinting upon sheets oreal-ds of coloreddesigns by means of stenelhng,1n which-process the sheets o1' cards :1re urrungel'l in a vpile thedesign is applied b v means of coloring matter 4tlnongh :i steneihthestencil is then rein'ovedandthe top sheet. or card is teken fronithepile. .ln -fcoinieetion with' such' processes 1t. is neces-' .snryT-thn-t the ren-mining' sheets or cards be 'left' u inlistnrlml; end .inorder' to accolnplish this und :1tlhe sznne time remore the printedsheet or wird expeditiously :ind positir'elv, l mathe use of the .nleeh'einism een sist ig essentially o- :ty-htndle adapted to be held inthe hund ofthe opera-tor, such handie being 'prei-dried 'Avit-hconnection vto n. suitablesoure .ofjsuetion rnd provided also with aregulating valve' conveniently pla-eed' to be operated 'byione oftheii'geisof' the hand holding the. tool.

ticular construction, but desire t'o claim any equivalent that willsuggest itself to those skilled in the art,

What 1 claim is:

1. A portable sheet or card'lifter comprising a tubular handle having adownturned end, a flexible soft tube extending from said end, means forconnecting the other end'of said handle-with a suction device, a shorttube closed at one end intersecting said -tubular handle, said tubehaving alining ports to complete the passageway through the handle, aplunger valve insaid short tube for controlling said ports, a plughaving an opening therethrough screwed in the 4 lower ond ofsaid shorttube, a spring'in said short tube for niaintaining said plunger valve inposition to close the port toward the. suction device, the otherportbeing partly open to connect-tl1e free end of said tubular.

handle with the atmosphereY through ysaid plug, and a button connectedwith ,said plunger valve by a rod passing` through the closed end ofsaid short tube, depression ot' said button causing the opening ot theport toward` the suction device, exclusion of the atmosphere, andeffective connection hetween snid two ports.

2. A portable Vsheet or card litter, com- -prising a tubular handlearranged at' one end for connection with a suction device and at itsother-end forcontact with sheets or cards, a short tube closed 'at oneend intersecting said tubular handle,-said short tube havingl aliningports which complete the passageway through the handle, a plunger valvein said shorttube for controlling said ports, and meanssi'or maintainingSaid plunger. valve in position to close the, port toward thcsuctiondevi'ce, the otlierport bcing partly open to connect the free endot such tubular. handle with.themtmosphere through the open i dofsuchtubc, actuation cof said 4plunger causing the opening of the porttoward the section device, cxcl nsion oft the atmosphere and effectiveconnection between such -twol ports.
